Using Python

Sobel edge detector.

You need to implement your own 3x3 Sobel filter. Again, youmust not use any inbuilt

edge detection filter. The implementation of the filtershould be clearly presented with

your code.

Investigate the accuracy of the Sobel filter in terms ofpredicting the orientation of the

edge. If it is used for edge detection, what might cause anyinaccuracy of the edge

orientation estimation that you see? Look at the histogramof the gradient orientation

and find out the major edge orientations in the image.Please discuss whether the

gradient orientation histogram aligns with the real expectededges for the image or not.

You can use the inbuilt Sobel to discuss thisquestion.
